Prediction of pressure drop by wall friction and at geometric discontinuities is important in
nuclear thermal hydraulics simulation. Pressure-drop models were established and …

Nuclear power plants (NPPs) produce large amounts of spent fuel while generating
electricity. After the spent fuel is taken out of the reactor core, it still has a high decay heat …

Abstract Computational Fluid Dynamic (CFD) codes are a widely used tool in spent nuclear
fuel dry storage systems applications. A recurrent simplification used in most spent nuclear …

Single-phase water flow in rod bundles plays a crucial role in removing the heat generated
in the nuclear reactor core. The design and safety analysis of light-water nuclear reactors …

Abstract Changes in fuel assembly roughness caused by crud deposits can influence the
flow resistance characteristics of the fuel assembly. The existing correlations cannot …

During a loss-of-coolant accident in spent fuel pools, the fuel assembly will be exposed to
the air environment and decay heat will be removed through the natural circulation of air …

Liquid lead-bismuth eutectic corrosion and the deposition of corrosion particles can lead to
surface roughening of rod bundles, which impacts the convective heat transfer …

This paper presents a numerical investigation involving Direct Numerical Simulations (DNS)
of natural convection occurring within mixed domains of porous and pure fluids, featuring an …

During a loss-of-coolant accident in spent fuel pools, the fuel assembly will be exposed to
the air environment and decay heat will be removed through the natural circulation of air. In …

The fuel assembly in the reactor undergo surface roughening due to fouling deposits and
material corrosion, which significantly impact the pressure drop and convective heat transfer …
